Outline
The following operation allows the alignment of the shutter
speed of the camera with the variable scanning rate of a
computer monitor or display.
When a computer monitor screen or display is shot with the
camera, a bright horizontal line indicating excessive exposure
is displayed in cases when the scanning rate of the monitor
is faster than the shutter speed of the camera. A dark
horizontal line indicating insufficient exposure is displayed in
cases when the monitor's scanning rate is slower than the
camera's shutter speed.
The scanning frequency of a monitor varies due to various
reasons during the computer operation. Adjust the scanning
rate to obtain a stable image while observing the image in
the viewfinder.
